Unit Explanations
PoiseP
Source UnitThe poise (symbol: P) is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system of units. It is defined as the viscosity of a fluid that exerts a shear stress of one dyne per square centimeter when a velocity gradient of one reciprocal second is applied. In essence, one poise corresponds to a viscosity of 1 g/(cm·s). This unit is particularly useful in fields involving fluid mechanics and rheology, where the flow properties of liquids are analyzed.
Current Use
The poise is commonly used in laboratories and industries that deal with fluid properties, such as food processing, pharmaceuticals, and materials science. It is particularly relevant for measuring the viscosity of non-Newtonian fluids and biological fluids, such as blood, where understanding flow behavior is crucial. While the SI unit pascal-second is preferred in many scientific contexts, the poise remains popular in specific applications.
Fun Fact
The poise was historically significant in the study of blood flow, influencing medical research and treatments.
KilopoisekP
Target UnitThe kilopoise (kP) is a unit of dynamic viscosity, which quantifies a fluid's resistance to flow. It is defined as 1,000 poise, where one poise (P) is equivalent to 0.1 Pascal-seconds (Pa·s). This unit is used primarily in the field of rheology, which studies the flow and deformation of matter. The kilopoise is particularly useful for measuring the viscosity of thicker fluids, such as gels and heavy oils. Viscosity is a critical parameter in various industries, including food, pharmaceuticals, and materials science, influencing processes like mixing, pumping, and heat transfer.
Current Use
The kilopoise is widely used in several industries, including food processing, cosmetics, and pharmaceuticals, where it is crucial to understand the flow characteristics of substances. For instance, it is essential in formulating products like lotions, sauces, and paints, ensuring the right consistency and application properties. Laboratories frequently utilize the kilopoise in rheological testing to assess the performance of materials under various conditions. Additionally, the unit aids in quality control processes, helping manufacturers maintain product standards.
Fun Fact
The viscosity of honey is about 2,000 to 3,000 poise, which is why it flows more slowly than water.

Poise
viscosity • Non-SI
Definition
The poise (symbol: P) is a unit of dynamic viscosity in the centimeter-gram-second (CGS) system of units. It is defined as the viscosity of a fluid that exerts a shear stress of one dyne per square centimeter when a velocity gradient of one reciprocal second is applied. In essence, one poise corresponds to a viscosity of 1 g/(cm·s). This unit is particularly useful in fields involving fluid mechanics and rheology, where the flow properties of liquids are analyzed.
History & Origin
The poise was named after the French scientist Jean Louis Marie Poiseuille, who made significant contributions to the study of fluid dynamics in the 19th century. His work focused on the flow of liquids in tubes, and he is best known for deriving Poiseuille's law, which describes the laminar flow of incompressible fluids. The term was introduced in the 19th century and has been widely used in scientific literature since then, particularly in relation to the study of blood viscosity and other biological fluids.
Etymology: The term 'poise' is derived from the surname of Jean Louis Marie Poiseuille, reflecting his foundational work in fluid dynamics.
Current Use
The poise is commonly used in laboratories and industries that deal with fluid properties, such as food processing, pharmaceuticals, and materials science. It is particularly relevant for measuring the viscosity of non-Newtonian fluids and biological fluids, such as blood, where understanding flow behavior is crucial. While the SI unit pascal-second is preferred in many scientific contexts, the poise remains popular in specific applications.
💡 Fun Facts
- •The poise was historically significant in the study of blood flow, influencing medical research and treatments.
- •One poise is equivalent to 0.1 pascal-seconds, showing the relationship between CGS and SI units.
- •The term 'centipoise' (cP) is commonly used in industries, where 1 P equals 100 cP, making it easier to express lower viscosities.

History & Origin
The concept of viscosity dates back to ancient civilizations, but the formalization of the unit 'poise' was established in the 19th century by French physicist Jean Léonard Marie Poiseuille. The kilopoise emerged as a convenient scale for higher viscosity values, especially in industrial applications where fluids exhibit significant resistance to flow. It allows for easier handling of large numerical values in viscosity measurements.
